Description

Technical Field

[0001] The present application relates to a brush presser foot mechanism, belonging to the technical field of flat knitting machines. Background Art

[0002] When a flat knitting machine is performing knitting work, a brush device is required to open the needle tongue. A traditional brush device cannot avoid the yarn clamped by the scissors device, causing the yarn to escape from the scissors mechanism.

[0003] Therefore, in order to solve the above technical problems, it is necessary to provide a brush mechanism to overcome the above defects in the prior art. Utility Model Content

[0004] The utility model aims to provide a brush mechanism for avoiding yarns.

[0005] To achieve the above-mentioned purpose, the technical solution adopted by the utility model is: a brush mechanism, including a casing, the casing is installed above the flat knitting machine, and also includes a brush and a brush control mechanism. A sliding plate is installed on the top of the brush, the sliding plate is slidably connected in the casing, the brush is facing the flat knitting machine, and the brush control mechanism is installed on the casing. The brush control mechanism drives the brush to slide back and forth along the sliding direction of the sliding plate through a swing arm.

[0006] By adopting the above technical solution, when in use, the brush can slide back and forth along the sliding direction of the sliding plate, so that when the scissors mechanism clamps the yarn, the brush can move upward to avoid contact with the yarn.

[0007] A brush mechanism of the utility model is further configured as follows: a slide groove is provided in the sliding plate, a fixing rod is fixedly connected in the housing, and the slide groove cooperates with the fixing rod.

[0008] By adopting the above technical solution, the sliding plate can move back and forth along the direction of the sliding groove.

[0009] A brush mechanism of the utility model is further configured as follows: the casing comprises a base and a pressing plate, and the pressing plate is mounted on the base.

[0010] By adopting the above technical solution, the pressing plate can limit the moving range of the sliding plate.

[0011] A brush mechanism of the utility model is further configured as follows: a movable groove is provided at a connection between the pressing plate and the machine base close to a side of the brush control mechanism.

[0012] A brush mechanism of the utility model is further configured as follows: a driving plate is fixedly connected to the sliding plate, and the driving plate extends out of the casing through a movable slot.

[0013] A brush mechanism of the utility model is further configured as follows: a driving groove is provided at one end of the driving plate close to the brush control mechanism.

[0014] A brush mechanism of the utility model is further configured as follows: one end of the swing arm is connected to the output shaft of the brush control mechanism, and the other end is located in the driving groove.

[0015] By adopting the above technical solution, when the swing arm rotates, it can drive the drive plate to move, thereby linking the movement of the bristles.

[0016] A brush mechanism of the utility model is further configured as follows: a Hall sensor is arranged between the machine base and the sliding plate.

[0017] By adopting the above technical solution, the Hall sensor can reflect the sliding state of the sliding plate.

[0018] A brush mechanism of the utility model is further configured as follows: an air blowing component is arranged outside the pressing plate, and the air blowing component faces the brush.

[0019] By adopting the above technical solution, the air blowing component can clean dust.

[0020] Compared with the prior art, the utility model has the following beneficial effects:

[0021] The brush in the utility model can slide back and forth along the sliding direction of the sliding plate, so when the scissors mechanism comes over to hook the thread and cut the thread, the brush can push the woven thread away, and the degree of automation is higher.

[0028] Please refer to the instruction manual Figure 1To Attachment Figure 6 The utility model is a brush 1 mechanism, comprising a brush 1 and a brush control mechanism 2, through which the brush 1 slides.

[0029] A swing arm 3 is fixedly connected to the output shaft of the brush control mechanism 2, and a driving plate 4 is provided at the end of the swing arm 3. A driving groove 41 is provided at one end of the driving plate 4 close to the swing arm 3, and the other end of the driving plate 4 is connected to the sliding plate 5 through a bolt and nut structure. The swing arm 3 cooperates with the driving groove 41, and a sliding groove 51 is provided on the sliding plate 5. A fixing rod 61 is fixedly connected to the base 6, and the fixing rod 61 cooperates with the sliding groove 51. The brush control mechanism 2 controls the swing arm 3 to make a circular motion, and the swing arm 3 links the driving plate 4 and the sliding plate 5 to move along the length direction of the sliding groove 51. As a preferred embodiment, the length direction of the driving groove 41 is perpendicular to the length direction of the sliding groove 51.

[0030] A pressing plate 7 is installed outside the base 6, and the pressing plate 7 can limit the moving range of the sliding plate 5. A movable groove 71 is provided at the connection between the pressing plate 7 and the base 6 near the brush control mechanism 2, and the movable groove 71 provides space for the driving plate 4 to slide. A Hall sensor 8 is provided between the base 6 and the sliding plate 5, and the Hall sensor 8 can reflect the sliding state of the sliding plate 5. A blowing component 9 is provided outside the pressing plate 7, and the blowing component 9 faces the brush 1. The blowing component 9 can clean dust. The pressing plate 7 and the base 6 constitute a housing.

[0031] The working principle of a brush 1 mechanism of the utility model is as follows:

[0032] When pressure is needed, the brush control mechanism 2 is started, and the brush control mechanism 2 controls the swing arm 3 to make a circular motion. The swing arm 3 links the driving plate 4, the sliding plate 5 and the brush 1 to move along the length direction of the slide groove 51. When the brush 1 moves to the top of the slide groove 51, it avoids the scissors device 2' and the yarn 1'.
